T0 @ZZ whom t may concern:

Be it known that I, FRANKLIN G. PALMER, a citizen of the United States, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Vapor Stoves, of which the following is a specification.

My invention relates generally to stoves in which oil is employed as the fuel and led from a reservoir to a burner where it is transformed into burning vapor.

It is the object of my invention to form an oil stove in such manner, and to provide in connection with it such a torch and such torch-saturatin g devices as will permit of the stoves being put in operation with readiness and certainty. Further objects are the provision of a simple and effective valve to control the supply of oil to the stove,and of a device for guiding the torch to the stove burner and for retaining said torch in position to occasion the heating and ignition of the oil supplied to said burner.

In the drawings,

Figure 1 is a view in perspective of a stove embodying my invention. l

Figure 2 is a detail view in side elevation of the burner pipe, its valve, the burner, and the torch guide. v

Figure 3 is a plan view partly sectional of a portion of the burner pipe, its valve, the torch receiver and the torch guide.

Figure 4 is a view similar to Figure 2 illustrating however a modied form of torch guide.

Figure 5 is an elevational view of the devices shown in Figure 4E, sight being taken from the right hand side of said Figure 4, and the valve operating head L2 being supposed removed.

Figure 6 is a central vertical sectional elevation through the torch holder. Y Figure 7 is a longitudinal sectional elevation through the cap of the torch, and illustrating the application to said cap of the rod and its nut, and the asbestos packing.

Figure S is a sectional' plan view of a modiiied form of valve for the burner pipe.

Figure 9 is a detail view of the head of the valve shown in Figure 3.

Figure 10 is a view of a torch receiver embodying a vside pocket, and equipped with an outlet pipe.

Similar letters of reference indicate corresponding parts.

In the drawings, A is the frame work of the stove, being, as such, of any preferred character,-that shown consisting of a flat top d supported upon standards ctx. This top embodies the usual grated opening (d, beneath which is situated the burner, described hereinafter.

B is a permanent oil reservoir, being a holder of any preferred construction, which is supported, as is customary in stoves of this character, in a position above or distant from the stove proper so as to avoid undue heating of its contents, and also so as to occasion the feeding of its contents to the stove by gravity.

F is a pipe the central portion of which is supported upon the standards of the stove. One end portion, FX, of this pipe is carried upward from the stove, and upon its eX- tremity is mounted the reservoir B hereinbefore described. This end portion F serves not only to support the reservoir, but also, by being in communication with its interior, serves as the channel through which its contents gravitate to the stove. The other end portion, F', of the pipe F is also carried upward, preferably from another part of the stove, and upon its extremity is mounted a torch holder, G, being a container of shape suitable to receive the torch employed, and in communication with the pipe.

It will now be understood that oil deposited in the reservoir B will normally, by reason of the communication established through the pipe F, exist upon the same level in both the reservoir and the torch holder.

The torch-holder G is preferably supported in such position that its bottom occupies a level slightly lower than that of the reservoir B, but the end of the pipe member F opens through the side of said holder G forming a port opening at a point above its bottom and about on a-level with the bottom of the reservoir B,-with the result that a pocket is formed in the bottom of said holder. Y It will therefore be apparent that when the oil reaches the level of the bottom of the reservoir B and the open end of the pipe end F,-

IOO

it will, in the further operation of the stove, cease to run out of the holder G, and in consequence the oil contained therein below the level of the end of the pipe member F will be retained for the uninterrupted saturation of the torch.

H is the burner supply pipe, which is in communication with the pipe F. This pipe H from the point where it taps or is joined to said pipe F leads at some radial distance from the burner, upward almost to the' grate, Where it bends abruptly and returns downward, in such manner that it does not cross the burner, both members of the elbow or return bend 7b3 being so formed as to be upon the same side of the burner. The lower end of the downwardly bent pipe is at the proper level horizontally extended to the discharge nozzle, but preferably embodies in its horizontal extension hX, an elbow, h, in connection with which elbow is also formed a boss h2.

I is the discharge nozzle or burner, being a short vertical tube formed upon the eX- tremity of the pipe I-I, and constituting a continuation of the same. The lower end of this nozzle depends below the burner pipe. .I is a pan or receiver, surrounding and connected with the lower portion of the burner I. In the ordinary form of vapor stove this pan is employed to contain a small quantity of oil, which when it is desired to put the stove in operation, is ignited and heats the burner and discharge nozzle, so that when the oil is turned on the latter is by contact with such heated parts and by the heat from the iiame, vaporized, and the vapor set on fire. lVhen the ordinary form of pan is used, however, it sometimes happens that when the parts of the burner become heated, large flames shoot up through the centre of the burner, accompanied by slight explosions. To obviate this I have devised the plan of forming in the margin of the pan a deep pocket j, as shown in Figure l0, which receives a great part of any oil placed in the pan, with the result that in operation the oil in the main body of the pan is first consumed, and by the time the parts of the burner become heated only the oil contained in said pocket remains, and said pocket, being radially separated from the burner, the iiame rising from the oil which it contains is at such distance from the burner as to avoid the creation of the large flames 1nentioned.

J X, Figure lO, is an outlet pipe leading from the pan, at a point near the upper edge of the latter, to a reservoir or receptacle of any suitable character.

Stoves of this character are sometimes inadvertently extinguished without their flow of oil being stopped, and said pipe J X is provided for the purpose of collecting the oil which continues to flow after such extinguishment and conducting it to a place of storage.

K is a vertical stem, depending from the lower end of the burner, provided with an operating head K', and intended to operate a burner-cleanin g needle which works within the nozzle I in the manner usual in stoves of this character.

In connection with the burner supply pipe, I apply at the elbow and boss in the horizontal portion thereof a key or valve of a novel construction. The boss 7b2 referred to has a screw-threaded exterior, as shown in Figure 2, and is interiorly bored out to form a cylindrical seat the inner end of which is conical and opens into the bore of the burner pipe II. Il is a key, the enlarged head Zof which is shaped to accurately fit said seat. LX is a cap, embodying an aperture fitted to the stem er shank of the key, and being screw threaded to engage with the exterior thread of the boss. This cap is adapted when screwed upon said boss to bear against the rear portion of the head of the key so as to maintain it firmly, but free for rotation, within its seat. The advance end of the head will, when said head is forced home to its seat, extend into and across the bore of the burner pipe. L is a channel cut through the substance of the advance end of said key, so that, when the key is in a given position, the channel registers with the bore of the burner pipe and permits the passage of its contents,-but when said key is rotated away from such position, the substance of the key closes said bore and shuts oil the supply of the oil to the iiame. The outer end of the key stem is provided with a head IP for convenience of manipulation.

In Figure S I illustrate a slightly modified form of this valve. In said figure a bore, circular in transverse section, extends downward through the substance of a slight enlargement at the elbow z, the circumference of which (bore) reaches to the inner side of the channel of the pipe hX. M is a plug adapted to fit within said bore, and provided with a groove or channel 'm which by the rotation of the plug maybe thrown into or out of registry with the channel of the pipe. This plug is equipped with a handle MX, which passes through a slot m in the said enlargement, elongated to permit of the throw of said handle, to open or close the passage of the pipe.

To the upper end of the ret-urn bend h3 is, in any preferred manner, secured a bracket or arm which supports in position over the nozzle of the oil pipe a flame tube N and radiator O of the usual construction.

The burner pipe with its elbow and bends, as will be apparent, exists in this construction, at one side of the llame of the stove, thus leaving an unobstructed approach to the other side of the flame.

P is what I term a torch guide, the same being, as shown in the construction represented in Figures l, 2, and 8, a tube which may be fashioned in any convenient manner, and which is conveniently supported in the frame-work of the stove. The guide is pref- IOO IOS

IIO

erably supported in an inclined position within the open space at one side of the ame which this construction of stove provides, as described,-and as to its inner end terminates just over the receiver J, when such receiver is employed, while its outwardly and upwardly extending body terminates conveniently just outside of the frame-work of the stove.

As an equivalent of this construction the arrangement represented in Figures 4t and 5 may be resorted to, in which in the stead of said inclined tube P, is employed a shelf Q, which, similarly, leads to the receiver, if a receiver is employed, and similarly terminates outside of the frame-work of the stove. The shelf is preferably formed of sheet metal, and both of its edges are upturned, that nearest the burner, q, being but slightly upturned, and that farthest from the burner, q', being upturned to a much greater extent. The object of turning up the edges of the shelf is to furnish a guide for the insertion of the torch and to keep the wind away from it.

R is the torch, the same being preferably constructed as shown in detail in Figure 9 of the drawings, in which r is a handle rod, one end of which is screw threaded, and rx is a cylindrical cap, one end of which is constructed to form a neck which is threaded to screw upon said rod. r is a mass of fibrous asbestos or other suitable material packed within so as to fill said cap and to surround the contained end of the rod r,- While r2 is a retaining nut screwed upon the end of said rod and serving to retain said asbestos in position.

The torch is ordinarily stored in the torch holder G hereinbefore described, in which it is kept constantly saturated with the oil therein so as to become very inflammable. When it is desired to start a fire in the stove, the torch is withdrawn from its holder, is ignited by a match or otherwise, and is inserted in the torch guide or holder in proper position for its flame to vaporize the contents of the pan or receiver and eventually ignite the Ilow from the discharge nozzle. The torch when placed within or upon the torch guide and pan, or upon the torch guide alone, is left in such position, and maintained by the torch guide until it effects the desired ignition.

IVhen the torch guide formed as a shelf is employed, the npturned edge q should be cut away in the neighborhood of the burner so that it will not interfere with the contact of the torch with the said burner.

Having thus described my invention, I claim- I. In an oil or vapor stove, in combination, a burner, an oil reservoir, and a torch holder, said oil reservoir and torch holder being in communication with the burner and with each other, substantially as set forth.

2. In an oil-or vapor stove, in combination, a burner, and an oil reservoir and a torch holder in communication with said burner and with each other, the torch holder being a receptacleadapted to contain oil and a torch and its communication with the reservoir and burner being established through an opening formed in its side, substantially as set forth.

3. In an oil or vapor stove, in combination, a burner, an oil reservoir embodying an opening in its bottom, a torch holder the bottom of which occupies a lower level than the bottom of the reservoir, and which holder embodies in its side an opening at approximately the level of the bottom of the reservoir, and a pipe connection between the burner and the openings of the reservoir and torch holder, substantially as set forth.

4. In combination with a vapor stove having a self generating burner in its central portion, a torch guide extending from the eX- terior of the stove to a point in the vicinity of said burner, and adapted to guide a torch to said burner and to support said torch in such position that its flame will heat said burner.

In testimony that I claim the foregoing as my invention I have hereunto signed my name this 13th day of October, A. D. 1890.
